"Riley is one of the toughest and hardest-working guys in our locker room," Eagles coach Chip Kelly said. "We talk a lot about how players have to make the most of their opportunities, and he did just that last year. He used his size, strength and speed to make a lot of big plays for our team and I'm excited to watch him build upon his success."

Added general manager Howie Roseman: "Riley's a tough player who can not only go up and catch the football and make big plays, but who also takes a great amount of pride in his ability to block and be physical down the field. He made the most of his opportunities last year and we all expect him to build upon that. Riley wants to be an Eagle and expressed that several times to us throughout this process. We were very excited to get this done before the start of free agency."

Kelce started every game last season after returning from a knee injury suffered the previous year.

"Jason is the epitome of the type of player we want around here, both on and off the field," Kelly said. "He's tough, extremely intelligent and is a leader by his actions and by his words. His athleticism is something that really sticks out when you watch him play. There aren't many centers that can get down the field like he does."

Added Roseman: "You just don't see many interior linemen with the athleticism that Jason Kelce possesses. It shows up on film many times where you just see him 10 or 15 yards down the field making blocks. His intelligence, work ethic and pride in his game are just off the charts. He's the proverbial gym rat and is always at the NovaCare Complex working on his game. This was the first off-season we had to re-sign Jason and we jumped all over the opportunity."
